I have a 2001 PT Cruiser and the odd time when I get in the car the car will not turn over. The remote unlock will not even work to opent the door. I turn the key and nothing happens, lights don't come on or anything. Get back in a few minutes later, it starts perfect. Not sure why those odd times the car in completely dead.
Also sometimes when driving the radio lights start to flash, some dashboard lights come on and then it goes away and everythign works fine.
